Definitions

  • the invention lies in the field of textile technology and relates to a method and a device according to the preamble of the two independent claims.
  • untwisted yarns can be produced from bundles of endless, synthetic fibrils in such a way that the mutual arrangement of the individual fibril bundles is constant.
  • Two or more bundles of endless, synthetic fibrils are continuously processed into untwisted yarns by combining them between the process steps of spinning and drawing or between drawing and texturing (for example gas-dynamic upsetting process) and possibly actively, for example by passing through an air jet, be mixed. If no special precautions are taken when merging and mixing, the relative arrangement of the original individual fibril bundles in the untwisted yarn produced is purely random and it changes with a random frequency, which also depends on its mean the environmental conditions during manufacture and manufacturing parameters such as the thread tension when merging or mixing. The relative arrangement of these bundles is irrelevant for yarns which are composed of identical fibril bundles, so that such a method is absolutely suitable for their production. This is not the case for yarns which consist of bundles of different colors or of different colors.
  • German patent DE 33 28 477 claims a method in which the mutual arrangement of the fibril bundles is changed in a controllable regular rhythm when the traversing thread guides are arranged accordingly.
  • yarns with a regular and, above all, reproducible color quality can be produced, which lead to regularly fine or coarsely mottled finished products.
  • the object of the invention is to specify a method and to provide a device for the production of yarns, from which products with such special, new color effects can be produced.
  • At least two bundles of endless synthetic fibrils should be joined together to form an untwisted yarn so that the mutual arrangement of the individual fibril bundles is always the same.
  • the degree of mutual mixing in the border zones between the individual fibril bundles should be controllable and reproducible.
  • the process should be able to be combined with conventional continuous processes for the production of synthetic yarns in such a way that the individual fibril bundles do not first have to be wound onto spools.
  • the device should be able to be installed in modules in existing devices for the continuous production of untwisted yarns.
  • FIG 1 shows the schematic sequence of the manufacturing process for untwisted yarns.
  • the main process steps are spiders 11, lines 12 and texturing 13, which are shown in the figure as solid, large boxes.
  • the intermediate process steps are shown as small boxes (broken lines), above the main process steps for the standard process according to the prior art and below the main process steps for four process variants according to the invention.
  • the fibril bundles emerging from the spinnerets are widened in a method step 14.1 to form a fibril ribbon in which the fibrils lie more or less next to one another and are oiled in this form.
  • a fibril ribbon in which the fibrils lie more or less next to one another and are oiled in this form.
  • no precautions are taken to guide the fibrils of the individual bundles separately, and mixing of the bundles is already possible.
  • the fibril ribbon is guided over a single-groove convergence thread guide (method step 17), the original fibril bundles being combined into a thread and losing their identity. Another oiling follows 14.2.
  • the fibril bundles, which are oiled twice and brought together, are fed into the path in this form. It is obvious that with such a method, not only the mutual arrangement of the individual bundles, but even the individual fibrils, when entering the path, is purely random and that it can change at purely random intervals.
  • Variant I of the method according to the invention provides for more intermediate process steps between spinning and stretching, all of which are aimed at the mutual position of the fibril bundles and the mutual mixing of the fibrils of the individual fibril bundles constantly hold so that the combined bundle fed to the route does not represent a mixture of the original individual bundles, but individual bundles guided absolutely parallel, the fibrils of which are not mixed in the border zones or are mixed in a reproducible manner.
  • the first intermediate step 14.1 of this variant of the method according to the invention is, like in the standard method, a reshaping of the fibril bundles into fibril bands and an oiling. Appropriate guidance of the ribbons and a wide oiling area ensure that the individual ribbons run separately next to each other.
  • the oiling 14.1 is followed by a separating step 15.1, in which the tapes are individually guided over separating pins in such a way that they are widened again into tapes, but which are rotated by 90 ° in relation to the tapes in the oiling step 14.1.
  • a second oiling 14.2 with an oiling surface that is perpendicular to the oiling surface for the oiling 14.1 follows the separation 15.1.
  • the still separate fibril bundles prepared in this way are now passed through a false twist stage 16.
  • This vortex of air causes the fibril bundles to undergo a false twist, which arranges the individual fibrils in such a way that they have less of a tendency to mix with the fibrils of the bundle running next in later procedural steps in which the individual bundles are guided parallel and closely next to one another.
  • This effect is exacerbated by the fact that the direction of rotation of the air vortex is opposite for neighboring bundles.
  • the subsequent tendency of the fibrils to mix can be controlled via the strength and quantity of the air flow.
  • the false twist step 16 is followed by a merging step 17 in which the previously separately guided fibril bundles converge in a groove of a thread guide.
  • the thread guide that brings the individual ribbons together is arranged and its groove is created so that the ribbons come to lie next to one another in a constant manner.
  • the material is fed to process step 12, the stretching.
  • Variant I of the method according to the invention produces a yarn which is characterized by minimal mixing of the fibrils of the individual bundles in their contact zones. As a result, clear color effects are created, and finished products made from such yarns are perceived as effectively multi-colored with high color contrast between the individual bundles. If mixing of the fibrils in the edge zones of the individual bundles is to be permitted for softer color effects, this can, as already mentioned, be achieved by a lower air flow for the force-fitting false twist device, or, as the process variant II shows, by complete Omit this facility. The effect of sharp color separation can also be increased by separating the individual bundles again after the merge in further separation steps 15.2 even before stretching step 12 and / or 15.3 between sections 12 and texturing 13. Such process variants are shown as variants III and IV in Fig. 1 shown.
  • FIG. 1 shows four variants of the method according to the invention as examples.
  • other arrangements of the method steps are also possible, for example by feeding the fibril bundles totally separately to the path 12 and only merging them between paths 12 and texturing 13 in a series of intermediate method steps.
  • FIG. 2 shows a comparison of an embodiment variant of the device according to the invention for performing method variant I (FIGS. 2a and 2b) and the standard device for performing the standard method (FIGS. 2c and 2d).
  • a variant for three bundles of fibrils is shown. This can be modified analogously for only two or for more than three fibril bundles. It is also possible to repeat the two arrangements shown in a mirror image in relation to the dash-dotted line. With such arrangements, two yarns can then be produced from two or more bundles of fibrils.
  • 2a and 2c are seen from a viewing direction perpendicular to the line in which the spinnerets are arranged, hereinafter referred to as nozzle line, FIGS. 2b and 2d from a viewing direction parallel to the nozzle line.
  • the fibril bundles a, b and c emerge from corresponding spinnerets, which are arranged in a line.
  • the nozzle line lies in the paper plane, for FIGS. 2b and d perpendicular to the paper plane.
  • the fibril bundles first run over an oiling head 21 and a thread guide 22 which follows shortly thereafter and consists of a ceramic pin. By running the bundles over the oiling head 21 and the thread guide 22, the bundles are broadened into ribbons in which the fibrils run more or less side by side.
  • process variant I FIGS.
  • the oiling head 21 and the thread guide 22 are parallel to the nozzle line and the oiling width is so large (eg 300 mm) that the individual bundles can be guided over them separately.
  • the tapes each run over a separating pin 23a / b / c. that is perpendicular to the nozzle line.
  • the ribbons between the thread guide 22 and the separating pins 23 first run as ribbons parallel to the nozzle line, then converge into bundles in order to be widened again into ribbons perpendicular to the nozzle line.
  • the ribbons still run separately into the grooves of separating rollers 24 and are combined again into bundles.
  • the false twist device follows the oiler 25, which will be discussed in greater detail in connection with FIG. 3.
  • the fibril bundles pass separately through eyelets of the false twist device.
  • the air vortex in the eyelets gives them a rotation which is stopped against the spinnerets by the separating rollers 24 or by the separating pins 23.
  • the frictionally twisted bundles run side by side between a pair of centering pins 27 and a further separating pin 28, which acts as a swirl stop in the direction against the stretching zone.
  • a thread cutter with suction 29 follows.
  • the thread guide 31 guides the thread combined from the originally three bundles of fibrils to the stretching zone via corresponding roller arrangements.
  • the oiling head 21 and the thread guide 22 are perpendicular to the nozzle line.
  • the individual bundles on the oiling head 21 lie one on top of the other or at will next to one another, and a mixed ribbon is already formed here, which is then also guided directly onto a single-groove convergence thread guide 24 '.
  • On the convergence thread guide 24 ' follows a thread oiler 25 for process variant I.
  • the other elements of the device in the thread direction are the same as for the device for process variant I, except that the false twist device 26 is missing and thus also the separating pin 28 which stops the false twist .
  • a comparison of the two devices in FIG. 2 shows that they can easily be arranged in the same spatial conditions, that is to say that existing arrangements can be converted, or that the device according to the invention and the standard device are combined into removable modules and as desired can be exchanged.
  • FIG. 3a shows a section perpendicular to the thread direction and FIG. 3b shows a corresponding section parallel to the thread direction through the false twist device 26.
  • the three fibril bundles a, b and c run from top to bottom through the three eyelets 35a / b / c.
  • the eyelets are slightly funnel-shaped at the thread inlet and thread outlet, so there is no sharp edge could injure the thread running through it. Air is blown into each eyelet from a central air supply bore 36 through an air duct 37a / b / c running tangentially against the eyelet (FIG. 3c).
  • the thread insertion slots 38a / b / c through which the bundles of fibrils are introduced into the eyelets, also open tangentially into the eyelets, they open into the eyelets on the opposite side, so that they disturb the air vortex as little as possible.
  • the thread insertion slots 38a / b / c are widened toward the outside of the pre-entangling device so that the bundles of fibrils can be easily inserted into them.
  • the direction of the air vortex (indicated by arrows) is opposite thanks to the corresponding arrangement of the air channels 37a / b / c and the thread insertion slots 38a / b / c in adjacent eyelets.
  • the thread guide has two grooves, so that it can guide 2 yarns, combined from 3 bundles of fibrils each.
  • the grooves 31.1 and 31.2 of the thread guide 31 are relatively wide and the contact surface G to prevent the thread from running apart slightly concave (recessed), so that the individual bundles of fibrils come to lie close to one another but do not lie on top of one another.
